Study on optimal bandwidth for microwave breast imaging

This paper investigates the role bandwidth plays in ultra-wideband (UWB) microwave imaging for breast cancer detection. Most UWB microwave imaging systems operate between 3.1-10.6GHz as the FCC has authorised unlicensed use in this spectrum. Whether this is the optimal bandwidth for microwave breast imaging remains an open question. Using signals of different bandwidth and spectrum, this paper provides a computational study using an anatomical realistic breast phantom on the detection and location ability of an imaging algorithm.
